Latin America has emerged as an epicenter of the COVID-19 pandemic. Brazil, Peru, and Ecuador report some of the highest COVID-19 rates of incidence and deaths in the region. These countries also face synergistic threats from multiple infectious diseases (that is, ecosyndemic) and quasi-periodic El Niño-related hazards every few years. For example, Peru, which is highly sensitive to El Niño, already copes with an ecosyndemic health burden that heightens during and following weather and climate extreme events. Using an ecosyndemic lens, which draws on a multi-disease hazard context of place, this commentary highlights the importance of El Niño as a major factor that not only may aggravate COVID-19 incidence in the future, but also the broader health problem of ecosyndemic vulnerability in Latin America.

拉丁美洲已成为COVID-19大流行的中心。巴西，秘鲁和厄瓜多尔报告该地区的COVID-19发病率和死亡率最高。这些国家每隔几年还面临多种传染病（即生态同病制）和与厄尔尼诺有关的准周期性危害的协同威胁。例如，对厄尔尼诺现象高度敏感的秘鲁已经应付了生态综合症状的健康负担，这种负担在天气和气候极端事件期间和之后加剧。该评论使用了生态同情透镜，该透镜借鉴了多种疾病的危害背景，强调了厄尔尼诺现象的重要性，因为它不仅是未来加重COVID-19发病率的主要因素，而且还危害生态同病的更广泛的健康问题拉丁美洲的脆弱性。
